TRAIL FOR THE CARRIAGES F GUNS MOUNTED ON WHEELS.

Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed January 3, 1906. Serial No. 294.391.

To all whom it may concern:

Be it known that I, CHARLES PROSPER EUGENE SCHNEIDER, a citizen of theRepublic of France, residing at Le Creusot, Saoneet-Loire, France, haveinvented a new and useful Trail for the Carriages I of Guns Mounted onWheels, which is fully set forth in the following specification.

The present invention has for its object a trail for the carriages ofguns mounted on wheels, permitting of speedily modifying the inclinationof the entire body of the carriage for the purpose of increasing theangle of elevation without the wheels leaving the ground. To this endthe axle is cranked in the manner of a bracethat is to say, the spindlesof the carriage-wheels instead of being in line with the body of theaxle which supports the gun-carriage are arranged at the extremity oftwo crank-arms carried by the said axle-body in such a manner that bycausing these cranks to angularly move around spindles turning in thehubs of the wheels the axle-body is raised or lowered, together with thecarriage that it carries. Accordingly within certain limits theinclination of the carriage is modified at will means being provided forlocking the cranks in the desired position. In practice only the twoextreme vertical positions of the cranks are' useful, so that the deviceprovides for looking the cranks upon the carriage in these twopositions.

A practical form for carrying the invention into practice is representedby way of example in the accom anying drawings.

Figure 1 is a general longitudinal elevation of a gun-carriage and ofthe gun carried by it mounted upon a trail of the novel kind, thespindle-supporting cranks being shown in the extreme lower position.Fig. 2 is a corresponding sectional elevation on the lines A A ofFig. 1. Figs. 3 and 4 are similar views with the cranks represented inthe extreme upper position. Figs. 5 to 8 show in detail, upon anenlarged scale, the axle and the corresponding part of the carriage withthe means for locking the axle to the trail. Fig. 6 represents a sectionon A A of Fig. 5. Fig. 7 represents a section on B B of Fig. 5. Fig. 8represents a similar section, the bolt being shown raised for thepurpose of raising the trail.

For facilitating the mounting the axlebody comprises two sockets a,united by a bolt 1). Each socket a has projecting from its outer end acrank 0, provided at its extremity with the spindle d. The axle-bodyformed by the two sockets a and the bolt 1) is able to rotate in thesleeve e, formed on the trailf or carried thereby.

In the constructional form represented the looking to the trail of thecranks c, and consequently of the cranked axle as a whole, is obtainedin the following manner: In a casing g, projecting laterally from eachor only one of the sockets a, is pivoted on a spindle h a bolt i,subjected to the action of a spring j, which tends to press it in thelocking direction. This bolt in the extreme positions of the cranks 0comes, respectively, opposite notches 1 or 2 of a plate 7c, carried bythe sleeve e. It will of course be understood that these notches mightbe formed in any other appropriate part of the carriage. In the bolt 'ithere is formed a recess m, in which there may be inserted the extremityof a lifting-bar n. (Shown in broken lines in Figs. 1 and 3.) By meansof this arrangement the pivoted bolt i acts simultaneously as a lookingmember and as a member for operating the axle. In order to displace theaxle from the position in Figs. 1 and 2 into that of Figs. 3 and 4, theend of the bar n is engaged in the bolt 2', which then occupies theposition of Figs. 5, 6, and 7. In the first place the bolt is lifted inorder to release it from the notch 1, causing it to move from theposition shown in Fig. 7 to that shown in Fig. 8. Then the bar isrotated in the direction of the arrow, Fig. 1, until the bolt comesopposite the notch 2. he bar it has then assumed the position it,

lhe manner of constructing the axle-body, the disposition of thelocking-bolts of the sleeve 6, and of the notched plate 7c may of coursevary without affecting the principle of the invention.

I claim- 1. In combination, a pair of wheels, a crank-axle on which thewheels are mounted, a trail revolubly supported on said axle, andlocking means for locking said axle and trail together for differentelevations of said trail.

2. In combination, a pair of wheels, a crank-axle. on which said wheelsare mounted; said crank-axle comprising two crankarms, each of said armshaving at one extremity a spindle engaging one of said wheels and havingat the other extremity a socket, and a rigid connection between saidsockets; a sleeve revoluble on said sockets, a

trail fast to said sleeve, and means for looking one or both of saidsockets to said trail for different elevations of said trail.

3. In combination, a pair of wheels, a crank-axle on which said wheelsare mounted; said crank comprising two crank-arms each of said armshaving at one extremity a spindle engaging one of said wheels and havingat the other extremity a socket, and a rigid connection between saidsockets; a sleeve revoluble on the same, a trail fast to said sleeve, aspring-pressed bolt for locking one or both of said sockets to saidtrail for different elevations ofthe latter, and means engaging saidlocking-bolt for rotating said axle.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
